Example 1 The default value of '15' (0000,1111 binary or 0F hex) makes all 4
inputs report closed contacts as true (1) and none of the inputs will
operate the actuator.
Example 2 The value 255 (1111,1111 binary or FF hex) makes all 4 inputs report
closed contacts as true (1) and all the inputs control the actuator in
their predefined way.
Example 3 The value 0 (0000,0000 binary or 00 hex) makes all 4 inputs report
open contacts as true (1) and none of the inputs will operate the
actuator.
Index 60 HW_DI-4 ESD/Net Disable
In the IQ3/IQT3/SI
3
/CK actuator this input determines the mode of operation for the ESD/HW_DI-4
remote input. The input can be used either to disable control of the actuator from the FF network, or
to act as an ESD/digital input. When this setting is made 'Active' the input will disable FF control of the
actuator when the contact input is detected as being logic 1. This feature is dependent of the Auxiliary
mask setting and can be configured as an NO or NC input. When the HW_DI-4 ESD / Net Disable
parameter is set to ‘1’, no hard-wired ESD will be available.
Index 61 to 64 Partial Stroke
The actuator may be instructed to perform a partial stroke that causes the valve to be moved from one
end position to an intermediate position and return to the original position. If the action takes longer
than the pre-set time then a timeout indication is given, showing there is a fault.
• Partial Stroke % Travel
This parameter sets the position to travel to when a Partial Stroke
command is carried out. The partial stroke can be initiated from either
the open or the closed position of the valve. The target position can be
any value in the range 1-100% where 1 % is near the closed position.
Note that the desired value to which the actuator is required to move
must be outside the deadband setting.
• Partial Stroke Limit
This parameter is used to set two values. The most significant bit in
the register is used to determine the starting position which can be
either the open position (1) or closed position (0) for the valve.
• Partial Stroke Timeout
The time in which the partial stroke must be successfully completed.
• Partial Stroke Status
Indicates the time and date for partial stroke test success and failures.
There are 2 fields within this parameter, one for success and one for
failure. The parameters are in date and time format.
